12 claims. (ci. "J4-fzs) Our invention relates to improvements indrivingj gears.

'The objects of our invention are:

To provide a. driving gear which will revolve two shafts simultaneously,one of said sha'fts having a continuous uniform rotary movement and theother shaft having a rapid reciprocating rotary movement combined with aslow, Substantially continuous progressive rotary movement in one ectionof reciprocation; to provide-simple means by which the rotating dolly ofa reciprocating washing machine can be given a progressive forwardmovement simultaneously with its reciprocating movement; to providemeans for rotating a shaft progressively forward and simultaneouslyreciprocating the shaft; to

provide a combined wormand worm-gear operable simultaneously as aworm-gear andJack and pinion, with means for\,siniltaneously rotating-20 and reciprocating the wdrm.

We accomplish these objects by the means illustrated in the accompanyingdrawing, in which,-

Figure 1 shows a longitudinal section of our 25 gear on the line I-I ofFigure 2;

Figure v2 shows a sectional elevation of our gear on the line 2.-2 ofFigure 1;

Figure 3 is a cross-sectional detail on the line 3 3 of Figure 2;

30j Figure 4 is a sectional detail of the brace, 2|,

on the line 4 4 of Figure 1.

Similar numerals throughout the several views.

Our apparatus comprises a housing, I, which 35 may be of cast-ironorother suitable material and 'which may be united to a rigid base orcover plate, 2, in any desired manner.

Integral with the main housing, I, we form a housing, la, forthedrive-shaft, 3, and worm, l,

,40 with suitable bearings, sa, formed therein, for the motor-shaft, 3,on one en d of which the'worm, l, is formed or splined orotherwisesuitably secured.`

The worm, 4, meshes with and drives the wormgear-wheel, 5, which issecured upon the lower end of the shaft, 6. The shaft, B, may beutilized to drive a wringer or other-apparatus.

A hub, 2b, is formed integral with the cover 50 plate, 2, 'whichcontains bearings, 1 an'd B, in

which the shaft, 6, revolves.

The wheel, 5, has' suitably secured thereto or formed integraltherewith, a bevel-gear-wheel,`9. A crank-pin, I3, is rigidly secured tothe wheel, 5, 55 concentricall'y with the bevel-gear, '9, through nforms a yoke, the two arms of which refer to 'similar parts which itpasses, and may be secured therein in:

any desired manner.

A rotatable shaft, I I, has one end revolvably mounted in one end of thebearing-block, I2, the other end of which forms a socket or bearing, I2a, which embraces the crank-pin, I3, while the intermediate portion,I2b, of the bearing-block, I2,

opposite sides of the bevel-pinion, III.

Upon the end of the shaft, ,I I, which acts as a connecting-rod, I mounta bevel-pinion, III, which is rigidly secured to the shaft, II, andmeshes with thebevel-gear, 9.

'I'he opposite end of the shaft, I I, has a worm, Il, formed thereon,which meshes with and actuates they wtorm-gear, IB, rigidly-mounted uponthe shaft, Il, f

'I'he shaft, Il, is splined or otherwise keyed to the wheel; I6, and thelower end of the shaft, jl, is mounted yin a bearing, I5, preferablyformed in tegral with the housing, I. An additional bearing, Il, isformed integral with the base or cover plate, 2, and forms an upperbearing for the shaft; Il, above the base or cover plate.

The upper end of the shaft, Il, may be united in any desired manner tothe lower end of any machine which it is desired to actuate thereby,

such as the dolly of a washing machine.

The worm, I1, is held in mesh with the gear,

I 9, by a sleeve, I9, in which it is slidingly andV revolvably mounted.The sleeve, I9, hasa lateral extension formed thereon, which is formedintegral with a collar, I9a, which is pivotally mounted upon the shaft,Il, above the gearwheel, I6. The sleeve, I9, is thus free to rock uponthe shaft, I4, as a pivot.

'Supports or braces, 20 and 2l, may be formed integral with the base orcover plate, 2, by which the base"plate, 2, can be rigidly secured tothe body of any apparatus which it is desired to operate, such as awashing machine body. l

The hub, 2a, may be threaded internally at its upper end to permit it tobe rigidly secured to the bottom of a washing machine 'tub or to anyother object to which it is desiredto attach it by any suitable form ofcoupling.

Inthe operation of my machine, the motor or other prime-mover upon theshaft, 3, may be started, causingthe shaft, 3, to revolve in eitherdirection' desired. As the shaft, 3,'revo1ves, the worm, l, will drivethe worm-gear-wheel, 5. As the w eel, 5. revolves, it will carry thecrankpin, I and the fixed bevel-gear', 9, around in a circle.

As the gear, 5 revolves, the gear-wheel,` 9.'

- gear, 5, may be varied by changing the relative diameters of thebevel-gears, 9 and III, and the length of travelof the gear, 9.

At the same time that the gear, 9, is rotating the gear, IIJ, thecrank-pin, I3, will be carrying the head, IZa, of the block, I 2, aroundin al circle,

which willcause the worm, I1, to slide backward' and forward in thesleeve, I9, and the worm, I1, will act as a rack to reciprocate theworm-gear, I6, which will act as a pinion. In the meantime, the sleeve.I9, will rock upon its` pivot, I4, so as to accommodate the variation inangle caused by the different positions of the crank-pin, I3, andconnecting-rod, II.

When the ratio of the bevel-gear, 9, and bevelgear, I0, is two to one,.the shaft, II, will be given two complete rotations with each rotationofthe shaft, 6, and the gear, l6, will accordingly travel a distanceequal to two spaces upon the worm, I1, in addition to the forward andbackward movement caused by therack and pinion action described.

It will thus be seen that with each reciprocation of the gear, I 6, itwill be advanced the distance occupied by two ofvits teeth and in caseof a washing machine, a dolly attached to the shaft, I4, will beproportionately advanced.

This action may be utilized and will be valuable in various types ofmachines, but has a particular value in the case of washing machinesbecause of the tendency of the clothes to pack and tear when thereciprocatory motion of the dolly is uniform. The effect of thisprogressive movement of the dolly which may be caused by our apparatus,will be to loosen up the-clothes when hunched and to prevent the packingthereof in-` side of the washing machine.

Our apparatus will also tend to prevent rolling the clothes in a machinein a ball, and will aid in keeping them separated so as to improve thewashing action thereof.

, It should be noted that whilewe have shown the drive-wheel, 5, and thedriven wheel, IB, as lying in the same plane, and the shafts, 6 and I4,as being'parallel, this arrangement is not necessary, but our apparatuswill permit a large variation in relative angle of these wheels andshafts so long as the axes of the shafts are kept at right angles to thelongitudinal axis of the connectingrod, II. v y

We do not limit our claims to the precise forms shown in the drawing, asit is obvious that vari-- ous modifications may be made withoutdepartying from the spirit of our invention, and our apparatus may beapplied to various types of machines in cases where a progressive rotaryaction is desired in connection with :a reciprocatory action.

Our apparatus is designed to be operated preferably by a reversibleelectric`v motor, but the shaft, 3', may be driven by any desired formof prime-mover and we do not limit our claims to an electrically drivenmachine.
